SPECIFICATION forming part of Letters Patent No. 443,722, dated December 30, 1890.

Application filed January 27,1890. Serial Nol 338,229 (No model.)

To alla whom it may concern: l

Be it known that we, FRANK. MARTIN and GEORGE MARTIN, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Fulling-Mills; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to fulling-mills; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings and subsequently claimed.

Inv the drawings, Figure l represents an elevation of our mill, partly in section; Fig. 2, a plan view, partly in horizontal section; and Fig. 3, a detail sectional View of one form of corrugated surface that constitutes part of our mill.

, Referringr by letter to the drawings, A represents two standards inclined toward each other and connected at the top by a crossbeam B to form the main frame of our mill. Pivotally connected to the cross-beam B are vertically-disposed arms C, shackled to pitmen D, that connect with the cranks l) of a shaft E, the latter having its bearings on posts F, connected to one of the standards A by means of a brace G, as shown by Fig. l.

The arms C extend down into a receptacle H and carry beaters I, the latter being tapered and corrugated at the ends. The receptacle H is provided upon its interior with a curved plate J, having a central opening c, and between this plate andthe bottom K of said receptacle we arrange a steam-coil L, for the purposes to be hereinafter described The bottom K of the receptacle is provided with a trap d to receive the dirt that is dislodged from the material under treatment and -falls through the opening c in the plate J during the operation of the mill. The plate J is not equal in length to the receptacle H, and eX- tending up from each end of said plate to the top of said receptacle is a corrugated surface in opposition to the ends of the beaters I, the latter being reciprocated in opposite directions bythe crank-shaft and pitman mechanism above described. As shown in Figs. l and 2, the corrugated surface consists of a series of ribbed rollers M, journaled in the sides of the receptacle H, and we prefer to provide each roller with a ratchet-wheel e for engagement with a spring-actuated dog f, whereby said roller is held against rotation except in the desired direction, the latter being the same for all the rollers iu the series. The corrugated surface may consist of a series of slats connected to endless chains or belts to form an apron R, that runs on rollers S, as shown in Fig. 3.

Our fulling-mill is particularly designed for the treatment of fur-skins, the latter being packed in a drystate between the beaters and the corrugated surfaces, steam let into the coil, and the crank-shaft rotated to reciprocate said beat-ers. Enough heat radiates from the steam-coil to melt the grease on the skins, and the latter, being pounded by the beaters against the corrugated surfaces, are softened by this mechanical treatment and by the absorption of said grease. The corrugated surfaces are rotated by the fric-tional Contact therewith of the fur-skins and the impact of the beaters, and said skins being constantly changed as to position by the rotation of the said corrugated surfaces the bunching that would otherwise result is avoided.

IVe are aware that the beaters and their actuating mechanismv are notnew of themselves, and we do not wish to be understood as claiming the same, except in combination with such other features as may be novel in the art to which our invention relates.

IVe are also aware that corrugated rollers are not broadly new in trilling-mills.

Having thus described ourinvention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a fulling-mill, the combination,l with reciprocating beaters, of corrugated rollers arranged in series opposite said beaters, ratchetwheels arranged on the rollers, and springactuated dogs for engagement with the ratchet-wheels, substantially as setforth.

2. In a fulling-mill, the combination of a receptacle, beaters reci procative therein, aplate of less length than the receptacle arranged in the latter beneath the beaters, a corrugated surface extended up from each end of the plate to the top of said receptacle, and a steamcoil arranged beneath said plate, substantially as set forth.

3. In a fulling-mill, the combination of a receptacle, beaters reeiprooative therein, a In testimony that We claim the foregoing; we io curved plate of less length than the reoeptahave hereunto set our hands, at Milwaukee, ole arranged in the latter beneath the beaters in the county of Milwaukee and State of Vsand provided with a central opening, a trap eonsin, inthe presence of two witnesses.

in the bottom of said receptacle in register FRANK. MARTIN. with the plate-opening, and a Corrugated sur- GEO. MARTIN. face `extended up from each end of the plate XVitnesses:

to the top of said receptacle, substantially as N. E. OLIPHANT,

set forth. WM. KLUG.
